Functions and Limitations of Use
When the instrument is correctly used, the dispensed liquid comes into contact with only the following
chemically resistant materials:
seripettor ® : FEP, PP, PE, EPDM
seripettor ® pro: PP, PE, Borosilicate glass, AI
2
O

ceramic, ETFE, PFA, FEP, PTFE, Pt-Ir
The bottle-top dispenser seripettor ® is designed for dispensing liquids directly from the reservoir bottle
and is offered in two models: seripettor ® and seripettor ® pro.
This instrument is designed for dispensing liquids,
observing the following physical limits:
– use between +15 °C and +40 °C (59 °F and
104 °F) of instrument and reagent
(seripettor
® : agar culture media up to 60 °C)
– vapor pressure up to 500 mbar
– kinematic viscosity:
2 ml instrument: 300 mm
2 /s
10 ml instrument: 150 mm 2 /s
25 ml instrument: 75 mm 2 /s
(dynamic viscosity [mPas] =
kinematic viscosity [mm²/s] x density [g/cm³])
– density up to 2.2 g/cm 3
Limitations of Use Operating Limitations
Liquids, which form deposits may accelerate wear
on the piston seal, and make the piston difficult
to move or may cause jamming (e.g., crystallizing
solutions or concentrated alkaline solutions).
When dispensing inflammable media, make sure
to avoid to buildup of static charge, e.g., do not
dispense into plastic vessels; do not wipe instru-
ments with a dry cloth.
The seripettor ® is designed for general laboratory
applications. Compatibility of the instrument for a
specific application (e.g., trace material analysis,
food sector etc.) must be checked by the user.
Approvals for specific applications, e.g. for produc-
tion and administration of food, pharmaceuticals
and cosmetics are not available.
